.. PRTG Manual: Login

For PRTG on premises instances, you can log in to the PRTG web interface once the PRTG core server is installed. In your browser, load the IP address or Domain Name System (DNS) name of the PRTG core server system and log in using the Login button. For PRTG hosted by Paessler instances, open your registered PRTG hosted by Paessler domain and log in to the PRTG web interface.

You can look up and change the web server settings of PRTG on premises instances at any time using the PRTG Administration Tool on the PRTG core server system. In particular, when you access PRTG from the internet, you should use a Secure Sockets Layer (SSL) encrypted connection. On the welcome screen, you can switch to SSL by clicking the Switch to SSL button under Enable SSL encryption for the PRTG website.

Loading the PRTG Web Interface

In a web browser window, enter the IP address or URL of the PRTG core server system. When using a cluster, connect to the master node. You can also double-click the PRTG Network Monitor icon on the desktop of the PRTG core server system. If you are using PRTG hosted by Paessler, enter the URL of your instance, for example myfirstdomain.my-prtg.com to access the PRTG web interface with a supported browser.

If you run PRTG on localhost, do not use the DNS name http://localhost to log in to the web server, as this may considerably slow down the PRTG web interface. Use your local IP address or http://127.0.0.1 instead.

If you see a certificate warning in your browser, you can usually just confirm it.

This only applies to PRTG on premises instances, not to PRTG hosted by Paessler.

After loading the PRTG web interface, the login screen is visible. You can either log in as default administrator or as any other user. As PRTG System Administrator user, you can use all functionalities of the PRTG web interface. Administrators can create additional users with administrator rights or with more restricted privileges (for example, read-only users).
